Method and apparatus for cross-hole pressing to produce cutting inserts |
摘要 |
A method and apparatus for the cross-hole pressing of cutting inserts is disclosed whereby a green part is fabricated using metallurgical powder and an opening is imparted within the green part by placing the metallurgical powder about an oval-shaped core rod. Using a press with a uni-axial press motion, a core rod is placed within the cavity of a mold and metallurgical powder placed around the core rod and thereafter compressed to form a green part. The subject invention is also directed to an article formed utilizing such a process and the uni-axial press used to produce such an insert.
